The paper focuses on preparing beta-titanium alloy Ti39Nb for nitrogen ion implantation, a process in which the surface is bombarded with nitrogen ions. To successfully introduce ions into the titanium surface, it is crucial to have a high-quality surface preparation. In addition to grinding and polishing, removing the mechanically affected surface layer is necessary to eliminate residual stress introduction by pre-treatments. In this case, the affected surface layer was removed using ion sputter-etching. Several analytical methods were chosen to characterize the state of the titanium alloy surface after ion sputter-etching. These methods included X-ray diffraction to verify residual stress removal, confocal microscopy, and atomic force microscopy to examine surface morphology. For experimental comparison to Ti39Nb, alpha titanium grade 2 was utilized.
